BLOCK OR BRICK MAKING MACHINE.

Application filed September 12, 1919.

T0 aZZ whom it may concern:

Be it known that I, RICHARD RYAN, citizen of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Block or Brick Making Machines,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to block or brick making machines and has specialreference to such a machine in which the aggregate employed thereinincludes cement, the product of which is commonly known as concrete.

While my invention relates particularly to a combination of mechanicalelements the employment of such mechanism involves a novel method whichforms a part of my present invention.

The principal object is to provide a simple and practical concrete brickforming machine.

Another object is the production of a novel and simple method ofsimultaneously forming concrete bricks and storing them in a steamingroom.

Still other objects and advantages of the invention will appear duringthe further description thereof.

In the accompanying drawings forming part of this application and inwhich like reference characters indicate like parts:

Figure 1 is a vertical sectional View through abuilding or room employedfor steaming concrete bricks during the production thereof.

Fig- 2 is a transverse sectional view of the brick-forming trough takenon the line 2-2, Fig. 1:.

Fig. 3 is a top plan view of Fig. 2 and Fig. 4 is a reduced plan view ofa build ing in which my brick-forming machine is employed.

1 represents a building of any desired construction built for thepurpose of steaming or otherwise treating bricks, such being common inthe art. In one end of this building I preferably provide an opening ordoor 2 sufiiciently large to receive the complete brick making machineand which may be placed within the building or removed therefrom asdesired or if, in the event of the employment of a large building havinga plurality of steaming rooms therein, the

machine may be transferred from one room to the other as is evident.

It is customary practice to form such bricks and subsequently transferthem to the steaming room, whereas in my present invention the bricksare formed as near as cated at at and the upper story is of sufficientheight to accommodate a suitable concrete mixer and the workingthereof,such a mixer being indicated at 5.

An open slot 6 is formed in the fioor 3 longitudinally of the room inwhich the bricks are to be stored, and a track 7 is provided adjacentthe slot for the accommodation. of the concrete mixer 5. A suitabletrack is also provided on the main floor of the building or room inwhich the bricks are being formed and stored. This track is for theaccommodation of the brick-making machine which is provided withsuitable wheels for cooperation with said track, or if found moreconvenient it is apparent that the tracks may be wholly dispensed withand both the brick making machine and the concrete mixer operated uponflat flangeless wheels if preferred. 2

In practising my novel method of making bricks which includes the curingof same in the steaming room, the first step taken is the passing of thebrick-making machine into the building or room in which the curingprocess is to take place together with the concrete mixer in the storyabove the brick machine and which latter, during the process of brickmaking is required to afford a continuous supply of concrete to themachine below, the mixed concrete passing through the slot 6 in thefloor 3. These machines are placed a suitable distance from the end ofthe building or room farthest from the entrance and convenient for thepi'lers to receive the bricks from the machine as they are formed andstack same in the end of the building or room. As the stacking or pilingup process of the bricks fill the room the machines are manually backedaway therefrom so that when the room is filled with bricks the machineswill be ejected, and ready for subsequent filling of the samecompartment or moved to other rooms or buildings for a like purpose.

It is not necessary to describe'the structure or operation of theconcrete mixing ma chine as such is not essential to this invention butthe brick-making machine involves novel combinations of parts that Iwill now proceed to describe, it forming an essential part of theinvention.

\Vithin the frame 4 is mounted a platform or table, sections of whichare indicated at 8, 9 and 10 and upon which is formed 7 a suitabletrough, the width of which is the exact length of the bricks to be made,said trough comprising the side walls 11, cooperating with the table topin forming said trough. In approximately the middleof the frame 1 aretwo large vertically spaced rollers 12 and 13 and upon either side ofthe latter are two vertically spaced smaller rollers 14., they being parallel with the roller 13 and but a short distance from either sidethereof. About these latter five rollers is placed a canvas or othersuitable belt, indicated at 15, and which passes over the sections 8 and9 of the bottom of the trou hand forms a movable bottom therefor.lDirectly above the section 8 of the table top is the feeding endof asuitable inclined spout 16 which feeds con crete. on to thebelt in thetrough. I have shown-at'17 a section of the wall of the spout 16 asbeing vertically reciprocable in any desired manner for the purpose ofgoverning the amount of concrete which is allowed to pass intermediateof the rollers 12 and 13 and by which it is obvious the density of thecomposition forming the bricks may be controlled.

An electric motor is indicated at 18 and drives a counter shaft 19 whichin'turn operates the feed roller 12 and upon the counter shaft 19 is anysuitable form of friction clutch pulley 20 controlled by the rope 21,such pulleys being capable of quick adjustment, as is well known in theart, and by which the roller 12 may be readily stopped and started. 1

It may be found necessary to apply power to some one of the rollers 13or 14:, but from experience thus far gained I am of the oplnlon it Willanswer every purpose to have power applied only to the roller 12 andwhich when in action will cause the belt 15 to revolve about the rollers13 and 14 as the concrete is carried forward in the trough.

At the end of the trough and adjacen the bottom section 10 is a framestructure indicated at 22 which supports a suitable platform for thereception of the pallets upon which the bricks are formed, one of 7same.

which is indicated at 23 is flush with the bottom of the trough and inreceptive positionfor the bricks... A laterally projecting extension 2 1is formed upon one side of the frame 22 which supports the series ofthin metal blades indicated at 25 which are designed to be manuallyforced through the body of concrete when the latter is in the trough onthe pallet and ready for forming into bricks.

The knives 25 are attached together at their outer ends by the'crossmember 26 which carries the operating handle 27 and may or may not bemounted upon suitable rollers or wheels 28 for convenience in reciprocalmanipulation. V

Slots 29 are formed in one of the side walls 11 of the trough dividingit into sections and which sections are held together by a superimposedmember 30, allowing the knives 25 to freely pass through when in the actof dividing the concrete within the trough.

The opposite side wallof the trough and for a distance the exact lengthof the pallet 23 as indicated at 31 is pivotally mounted upon suitablehinges 32 in the frame 22 and capable of being prostrated uponv thelaterally projecting extension 33 similar to the extension 24 the samebeing for the disposition of the pallet carrying the bricks formedthereupon.

Spring controlled dogs or catches 34 34 are mounted upon either uppercorner of the side section 31 of the trough and which dogs are designedto automatically catch over the stationary edges of the side wall 11adjacent the ends of the section 31 when the latter is in. its uppermostclosed position. These dogs are provided with forwardly extendinginclined portions 35 which are engaged by an inclined block 36 carriedupon the outermost ones of the knives 25, when the latter abut the innerface of the section 31. 1 By this engagement it is evident. that thedogs are obliged to release their hold upon the side 11 of the troughwhen the knives have fully passed through the contents thereof andonfurther advance of the knives 25 the section 31 will be prostrated toa position parallel and flush with that portion of the frame 22 uponwhich the pallet is supported, thus permitting of the pallet with itsload of bricks being forced directly. across said prostrated sectiononto the platform 37 provided forv On withdrawal'of the knives 25 thesection 31 will resume its position, forming a contlnuation of the sidewall 11, by the action of a suitable counter-weight 38 attached to thearm 39 and carried by the section, or any other convenient means forautomatically raising it. Then a fresh pallet. is placed within thetrough and the feeding along of the concrete therein again resumed bythe manipulation of the control of the friction pulley 20. When thepallet of bricks is thus prepared an attendant will place same in thepile of like units in the building or room where they are thus storedpreparatory to the steaming process.

It is evident that Various modifications and changes in the embodimentof the invention here shown may be resorted to without departing fromthe spirit thereof.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

The combination with a portable brickmaking machine of the characterdescribed having a suitable material feeding device associatedtherewith, of a downwardly inclined feeding spout in the brickmakingmachine, two vertically spaced feeding rollers adjacent the dischargeend of the spout, a trough intermediate of the rollers into which thespout discharges, an endless belt intermediate of the rollers, forming aportion of the bottom of the trough and onto which the material isdischarged from the spout, means for intermittently operating the brickmaking machine, means at the discnarge end of the spout and adjacent thefeed rollers for regulating the amount of material fed into the trough,and means at the opposite end of the trough for forming the contentsthereof into a plurality of individual parts, substantially asdescribed.

In testimony whereof I hereunto afliX my signature in the presence oftwo witnesses.
